Extensions Fuel Hollywood's Long-Hair Obsession

Just a couple of months ago, Victoria Beckham rocked a chic wavy bob—yet last week, her mane practically reached her waist!

Other recently short-haired stars like Ashley Greene, Anne Hathaway and Emma Watson have also popped up with longer locks. It's hard to imagine wanting longer hair given this heat wave, but for those that do, expert stylists are offering instant length.

Louise Moon of Sally Hershberger LA gave Greene extensions right after filming for Eclipse wrapped. For long-wearing strands of the "highest quality" (in other words, ultra real-looking), Moon says she uses Great Lengths pieces on all her celebrity clients. Instead of gluing, knotting, or welding, Moon attaches sections the width of your pinkie fingernail (or half that, if you have fine hair) using Great Lengths Air Pressure System. "It applies 10 extensions in 20 seconds, and the bond is extremely strong," says Moon. "It's normal to lose up to five extensions over the course of a few months, but I haven't had that problem with this machine."

With heat-sealed extensions like those done by Moon, your length can last up to four months. For a more temporary solution to stunted locks there are always clip-ins! Try Ted Gibson's or the ones from Hairdo.
